Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

A surgical simulator for peeling the inner limiting membrane during wet conditions. [PDF]

PLoS ONE, 2018
The present study was performed to establish a novel ocular surgery simulator for training in peeling of the inner limited membrane (ILM). This simulator included a next-generation artificial ILM with mechanical properties similar to the natural ILM that

Analysis of eye and head coordination in a visual peripheral recognition task [PDF]

, 2012
Coordinated eye and head movements simultaneously occur to scan the visual world for relevant targets. However, measuring both eye and head movements in experiments allowing natural head movements may be challenging.

Comparative evaluation of efficacy and safety of cyclosporine 0.1% add-on therapy with artificial tears (carboxymethylcellulose 0.5%) with artificial tears alone in post cataract surgery patients

National Journal of Physiology, Pharmacy and Pharmacology, 2018
Background: Cataract is the most common cause of preventable blindness and to surgically remove the affected lens and replace it with an artificial lens is the only effective treatment. Most patients post cataract surgery, complain of dry eye. Artificial
